Play / Play Scene should (optionally) open within a new tab instead of new window

Describe the project you are working on

2D Platformer and 3D RPG

Describe the problem or limitation you are having in your project

Using the Godot Edit in fullscreen and pressing the play or play scene button opens a new window. This has two downsides:

1. You are not able to see the output / debugger
2. It gets you out of the flow / focus that you have with the fullscreen mode, and is kind of annoying

This is especially the case on a macOS laptop where using fullscreen is very common but might be the case for Windows and Linux, too.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Instead of a new window, the game could launch within the editor in the main scene panel. Then the output / debugger, and also the other ui tools, are still visible.

I am pretty sure this is the case for Unity and Unreal, too.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

When the user presses play or play scene open within the editor. The option to do so might be configurable.

If this enhancement will not be used often, can it be worked around with a few lines of script?

No

Is there a reason why this should be core and not an add-on in the asset library?

This is about improving the editor usability

Duplicate of #1864. Currently Godot projects run as a separate process which cannot be embedded into the editor.

@pycbouh I dont know of this is actually a duplicate. The other issue is about way more features:

Add the ability to see how the nodes are behaving in the scene editor while the game is running.

I just want to play the scene in the editor, without any other feature requests.

You want exactly the same thing, just for different reasons.
